MT48LC8M16A2P-7E:L TR

The MT48LC8M16A2P-7E:L TR is a 128 Mbit synchronous DRAM (SDRAM) organized as 8M × 16 with a parallel memory interface. It operates with a 133 MHz clock and 5.4 ns access time, making it suitable for systems that require PC100/PC133-compatible SDRAM timing and standard commercial temperature operation.

This device is designed for integration in applications needing a 3.3 V supply (3.0 V–3.6 V), LVTTL-compatible I/O, and a compact 54-pin TSOP II (0.400", 10.16 mm width) package.

Key Features

• Memory Architecture  The device is organized as 8M × 16 (128 Mbit) with four internal banks to optimize row/column operations and hide row access/precharge latency.
• SDRAM Core  Fully synchronous operation with all signals registered on the positive edge of the system clock and internal pipelined operation allowing column address changes every clock cycle.
• Performance  PC100- and PC133-compliant timing; specified for 133 MHz clock frequency and 5.4 ns access time for the -7E speed grade.
• Burst and Refresh  Programmable burst lengths (1, 2, 4, 8 or full page) plus Auto Precharge, Concurrent Auto Precharge, Auto Refresh modes, and a 64 ms / 4,096-cycle refresh scheme.
• Low-Power and Self-Refresh  Supports Self Refresh Mode with both standard and low-power options, indicated in the datasheet options.
• Interface and Signaling  LVTTL-compatible inputs and outputs for standard 3.3 V system interfacing; single +3.3 V ±0.3 V supply.
• Package and Mounting  Supplied in a 54-pin TSOP II (400 mil) package suitable for surface-mount assembly; package width 10.16 mm.
• Operating Range  Commercial temperature grade specified for 0°C to +70°C (TA).

Typical Applications

• PC-Compatible Memory Subsystems  Suitable for designs targeting PC100/PC133 timing requirements where standard SDRAM timing compatibility is required.
• Embedded System Memory  Use as parallel SDRAM for embedded platforms requiring 128 Mbit density and LVTTL I/O at 3.3 V supply.
• Board-Level SDRAM Expansion  Compact 54-TSOP II package supports board-level integration where board space and standard commercial temperature operation are design constraints.

Unique Advantages

• Verified PC100/PC133 Timing: The -7E speed grade and 133 MHz clock rating provide compatibility with systems designed around PC100/PC133 SDRAM timing.
• Flexible Burst Control: Programmable burst lengths (including full-page) enable designers to tune throughput and latency to match memory access patterns.
• Power Management Options: Self Refresh and low-power modes reduce standby power and support systems that require power-aware memory behavior.
• Compact Surface-Mount Package: 54-pin TSOP II (0.400", 10.16 mm) simplifies PCB routing and assembly for space-constrained designs.
• Standard Voltage and I/O: Single +3.3 V ±0.3 V supply and LVTTL-compatible I/O ease integration into common 3.3 V platforms.

Why Choose IC DRAM 128MBIT PAR 54TSOP II?

The MT48LC8M16A2P-7E:L TR provides a straightforward, standards-aligned SDRAM solution for designs that require 128 Mbit density, PC100/PC133 timing support, and a compact TSOP II package. Its combination of internal banking, programmable burst lengths, and self-refresh options address common performance and power-management needs in commercial-temperature systems.

This device is appropriate for engineers and procurement teams specifying parallel SDRAM for embedded platforms, PC-compatible memory subsystems, or board-level expansions where 3.3 V operation, LVTTL I/O, and a 54-pin TSOP II footprint are required. Its documented timing and refresh behavior support predictable integration into existing SDRAM memory controllers.
